Chroma – a new way to build cameras

CCD/CMOS tiling has existed for ages. I don't understand what's new in this thing.

The technique you're referring to is aligning sensors over each other, each collecting a different color so you don't have to use a bayer filter (https://en.wikipedia.org/wiki/Three-CCD_camera). Chroma aligns multiple image sensors next to each other, to scale the resolution without increasing chip complexity. For instance, we can merge 4 4K sensors to create an ultra low cost 8K camera.

Nope.

I'm talking about having sensors next to each other. Very common in astronomical and medical (x-ray) applications at least.

Aligning multiple sensors next to each other has existed for at least 20 years, probably more.

  astronomical and medical

Sounds expensive! And when you tile sensors that way you still have gaps in between them. http://www.faculty.virginia.edu/rwoclass/astr1230/im/MegaCam...

We put off-the-shelf (cheap) sensors side by side with no gaps. Here's the patent if you'd like to read more: https://patents.google.com/patent/US20170359512A1/
